Dry, rough leaves? Form filled out...

This is my first time posting, so bare with me...

I had this problem about 2 weeks ago where the leaves are dry and have a rough texture. The problem seemed to have resolved itself and the plants were good for about a week. Today I noticed they're starting to get that texture again. I've searched the internet tirelessly and haven't found anything that may be similar to my issue. Anyone have any ideas?

Sorry about the quality of the pictures. My cell phone is a piece of crap. :cool:
